• Clay Davenport examined the drop in hitter production from AAA to the majors. From 2021 to 2025, he found the following adjustments.

Stat: Adjustment
AVG: -.040
OBP: -.046
SLG: -.099

Additionally, he found:

There is a small tendency for young players to do a little better than older players.

A good read on what has and hasn’t changed for hitters making that last transition to the majors.

American League

Guardians

• The team is going with a six-man rotation.

Cleveland will deploy a six-man rotation for the foreseeable future, manager Stephen Vogt said on Tuesday ahead of the Guardians’ 11-7 loss to the Red Sox. Joey Cantillo will start in Wednesday’s series finale at Fenway Park, joining Tanner Bibee, Gavin Williams, Cecconi, Logan Allen로건 and Parker Messick in the rotation.

“We’re going to go with the six-man rotation for a little while,” Vogt said. “Just with the starting pitching, where they are innings wise and where they are in their career. And we have 24 games in 24 days, so we thought it was a good opportunity for us to get them … they’ll all be on five days’ rest throughout this long process.”

Rangers

Jacob Latz will stay in the rotation.

Bochy said Latz will remain in the rotation for the foreseeable future, a relatively new development considering he has just six career starts in 78 appearances.

The last few weeks have been an adjustment for Latz, who didn’t even find out he was starting against the Diamondbacks until Monday. Even so, he said he was ready to go regardless of when his number was called, whether it was as a starter or out of the bullpen.

In five starts (23 relief appearances) this summer, the 29-year-old lefty has a 3.38 ERA (4.32 xFIP), 1.17 WHIP, and 7.5 K/9 in 24 IP.

White Sox

Brooks Baldwin adjusted his approach during the season.

But the switch-hitter also has executed something offensively that’s tough to do in-season – make meaningful changes to approach and technique and have them work immediately. Baldwin showed off those changes yet again with three hits against the Twins, as the White Sox (51-88) won for a third straight time and won a third straight game at Target Field (dating back to April 24) for the first time since 2021.

“It’s hard to adjust in season, but sometimes you have to do it when things aren’t going the right way,” Baldwin told MLB.com. “I made the choice to change and stick with it and go with it the rest of the year, and it’s done well.

“Just like the approach wise and kind of stance at the plate, spread out and get a little wider and shorten everything up a little bit and stay to the opposite field. It’s not really like I’m trying to hit everything to left field or left-center, but mentally I’m trying to stay on the ball that way. And then if it presents itself to pull it, you can still pull it.”

All his stats are showing 1H to 2H improvements

Stat: 1H, 2H
BB%: 5%, 8%
K%: 28%, 22%
OPS: .628, .802
Contact%: 77%, 80%,
avgEV: 90.4, 90.7

National League

Braves

Ha-Seong Kim 김하성 believes his struggles stem from coming back too early from his back surgery.

Kim believes coming back quickly from that surgery contributed to his back issues this season, but said he’s fine now.

Bryce Elder reworked his slider.

Elder noted the work on his slider as a reason for his stronger efforts.

He said he’d always thrown one that was “kind of nose-down gyro,” but that over time, he began to throw it differently. Elder “really looked into the nose being up, and the ball was just spinning right in the heart of the plate and people were hitting it.”

The slider was a pitch he felt was his top swing-and-miss offering, but he wasn’t getting those whiffs at the same level.

However, Elder has noticed progress with the slider since about the end of June. Six of his top seven single-game whiff rates with it this season have come since the calendar flipped to July — including Wednesday’s 38.4 percent — giving that credence.

I couldn’t find any signs of improvement on his end. Additionally, he is not throwing his slider as much. Before August 1st (beginning of Elder’s hot stretch), he threw his slider 38% of the time and 29% after that point.

Cardinals

Nolan Gorman implemented a change in early June.

Gorman didn’t play in any of the three games against the Royals. Instead, he took a couple of workout days in the batting cages and tried to put his trust in what felt comfortable. He ditched the toe-tap swing he started with at the beginning of the season and reverted to a leg kick while committing to a more selective approach.

Soon after, tangible results followed.

“Knowing where I was with playing time, I knew I couldn’t just go try to fix something every single day,” Gorman said. “I had to trust one thing and run with it. In Kansas City, that’s where I really started feeling good. That’s where I felt things really flipped. I was like, ‘I need to run with this, I need to keep it.’”

When evaluating Gorman, the Cardinals’ coaching staff likes to look at chase rate, strikeout percentage and walk rate to ensure Gorman is improving his plate discipline and fine-tuning his approach. Similar to nearly every power hitter in the modern game, with homers come strikeouts. Swing-and-miss will essentially always be a part of Gorman’s game, but it doesn’t have to define it.

Before the change, he was batting .187/.280/.297. Since the adjustment, .231/.329/.446.

• The manager wants Jordan Walker to take the team’s advice and improve several aspects of his game.

Not only would the Cardinals like to see a strong finish to the season from the former top prospect in MLB, but they also want to see [Walker] be more receptive to making the changes needed to potentially make him more consistent at the plate. And, quite frankly, the club’s patience seems to be wearing thin with the 23-year-old outfielder’s receptiveness to the changes they have asked him to make.

“We have not seen the consistency that we would have hoped for by now,” Cardinals manager Oliver Marmol said. “Our hope is that changes. He’s still young, and this could flip at any moment. We’ve seen other players where that’s the case — on this team or another — where they are an offseason away. But there’s real work to be done and there’s a real level of dedication and consistency that needs to come with that.

“I need to see Jordan have a sense of urgency for the things that need to take place to give him consistent results. That goes with his moves toward the ball, his preparation in the cage and his approach in games.”

“Real adjustments have to be made, physically and approach-wise,” he said. “[Brown] is doing a really nice job of providing him ways of doing that. Now, he has to take hold of that and put it in play.”

Cubs

Michael Soroka’s fastball velocity is in the mid-90s.

That’s encouraging since Soroka’s velocity dropped 3 mph after joining the Cubs

Dodgers

Roki Sasaki will remain in the minors to gain some consistency.

Given the results, and that the Dodgers have no immediate need for him at the big league level, it seems likely that Sasaki will remain with Oklahoma City for at least another start.

“Guys here are pitching well,” manager Dave Roberts said before Sasaki’s outing. “I’m not sure what that means for Roki after this one. Let’s just get through this one. Pitch well, [get] healthy, and then we’ll make a decision.”

After sitting around 96 mph with his four-seamer in his previous two starts, Sasaki averaged 94.4 mph with the pitch on Tuesday. He maxed out at 96.9 mph.

“The velocity needs to be consistent. The strike throwing needs to be consistent. Just having overall command,” Roberts said recently. “The focus certainly is different in the big leagues vs. Triple-A, which is totally fair. But I do think that where he’s at, performing and dominating Triple-A hitting is something we should expect.”

Teoscar Hernández’s groin and foot aren’t yet healed.

Concerns about Hernández’s focus go away if he’s hitting. This is not a storyline if he is putting up the .840 OPS he put up a year ago, or the .933 OPS he had before landing on the injured list in May with a strained groin. That halted what was set to be a strong encore to last year’s success. So did a bruise he suffered when he fouled a ball off his left foot more than a month after returning. The resulting struggles raised one of two questions: either Hernández was still hurt (or trying to avoid reinjuring himself) or the injuries had disrupted whatever rhythm he’d had to start the season.

Hernández’s groin and his foot are “100 percent,” he said.

“For me, it’s more being on the field,” Hernández said. “For me, being hurt is more frustrating than having a bad year. I’d rather be on the field and having a bad year than not being on the field and just fighting back and forth.”

Pirates

Nick Yorke will play some outfield.

Nick Yorke, the team’s No. 11 prospect according to MLB Pipeline, was recalled as part of the expanded September rosters and got the start at first base on Tuesday.

Yorke could also play second base and corner outfield, Kelly said pregame …
